Reason for Stuck on Sony Ericsson is that when you forget to check the USB debugging mode in development before flashing using the flash tool, thats why the tool is stuck on open source.
Resolution like you have selected downgrade kernel from the flash tool.. disconnect cable.. close flash tool. restart it. click flash and this time use upgrade kernel. and connect the phone using back button.
Phone will boot up again and you can now check the debugging mode in development and start root process again.
Enjoy
